I Looked Into Hoshino Resorts KAI Beppu
2026-09-08

On this blog, I mostly keep researching campgrounds and day-trip hot springs, but every now and then I go off on a tangent and look into hot spring ryokans and hotels as part of what I jokingly call my 'hokance' (hotel-vacation) side project. This is another one of those detours.
This time I looked into Hoshino Resorts KAI Beppu. I've always been curious about hot spring ryokans in Kyushu, and when I came across mentions of kaiseki cuisine featuring seafood from the Bungo Channel, I decided it was time to sit down and organize what I could find. I haven't actually been there myself—this is a summary based on information from the official website along with a check using Rakuten Mobile's signal-checking tool.
It looks like a hot spring ryokan whose main appeal is an indoor bath decorated with Usuki-yaki tile walls and kaiseki cuisine featuring seafood from the Bungo Channel.
The Rakuten Mobile signal check came back with a C rating, so if you're a subscriber or thinking about becoming one, it might be worth checking in advance for peace of mind.
I've summarized the details below.
I Looked Into What Kind of Ryokan KAI Beppu Is
Apparently KAI Beppu is a Hoshino Resorts hot spring ryokan located in the Kitahama area of Beppu City, Oita Prefecture. Check-in seems to be set at 2:30 PM, with check-out at 11:00 AM. The bathing facilities are prioritized for overnight guests, but it looks like day-use visitors can also use them, with same-day reception handled at the front desk.
As for rates, the official website doesn't list a fixed price table for one night with two meals—instead, prices seem to vary by date and room type, and you check them through the availability search system. Reservations themselves are made through the official site's availability search and booking system, and if you pay in advance, it looks like major credit cards, Paidy, and Eikyu Fumetsu Points are accepted. There also seems to be a phone reservation option, but I wasn't able to confirm the number.
- Number of rooms: apparently 68 rooms, accommodating 1 to 4 guests
- Main facilities: it seems there's a restaurant, café/lounge, spa/massage, kids' room, pool, hot spring, bathing facilities, and a meeting room
- Smoking policy: the whole building is non-smoking, apparently with a designated smoking area
- Wi-Fi: apparently free throughout the building
- Pets: limited to one room, apparently allowing up to two medium-sized dogs weighing 20kg or less
- Parking: no reservation needed and free of charge; if the on-site lot is full, they apparently direct you to a second parking lot (also free) about a 5-minute walk away. EV charging seems to be available 24 hours a day

Free parking with no reservation needed doesn't really affect me since I don't own a car, but I imagine it's pretty reassuring information for anyone driving there.
The Usuki-yaki Tile Walls and Bungo Channel Kaiseki Cuisine Look Like the Main Draws
The hot spring water is apparently a saline, sodium bicarbonate spring, and one of the biggest features seems to be the indoor bath, which has walls decorated with Usuki-yaki tiles depicting eight kinds of mountain flowers. Even just from photos, it looks like a space with a really distinctive atmosphere.
The meals seem to be centered around kaiseki cuisine using seafood from the Bungo Channel, where the Seto Inland Sea meets the Kuroshio Current from the Pacific, and there was also a mention of menus incorporating kabosu citrus and bamboo craftwork. Overall it gives an impression of food that really reflects the local character.
About the Regional Room "Kakishibu no Ma" and the Regional Entertainment
There's a regional-themed room called Kakishibu no Ma, and apparently all of these rooms have ocean views. According to the description, the design draws on the contrast between the persimmon-tannin (kakishibu) color inspired by the Chinoike Jigoku "Blood Pond Hell" and the ocean scenery, along with motifs from Bungo shibori tie-dyeing. It sounds like an interior that's quite conscious of local identity.
There's also apparently a form of regional entertainment featuring a performance called the "Toji Jug Band," where they play music using wooden tubs and hot spring water. I can only imagine what it's actually like in person, but it seems to be one of the highlights for guests staying there.
I Looked Into Access
The nearest station is JR Beppu Station, apparently about a 10-minute walk away. If you take the local bus, there's also guidance saying you'd get off around the Beppu Station to Beppu Kitahama area and walk about 1 minute, for a total travel time of roughly 10 minutes. Since I'm a non-driver with a license I never use, being within walking distance of a station is welcome information.
As for nearby sightseeing and dining spots, I couldn't find specific facility names or distance details on the official website, so there wasn't much I could write about with confidence—I'll leave that topic aside for this post.
Rakuten Mobile Signal Conditions
When I checked the location of KAI Beppu using the official "My Area Network Simulation" tool, the overall rating came back as a C.
Since the result was a C rating, it's probably worth checking the connection situation ahead of time. If you're planning to do online work or watch videos during your stay, it might be reassuring to prepare with this result in mind. Since Wi-Fi is apparently free throughout the building, relying mainly on a Wi-Fi connection when needed could be a good option.

A C rating is just something you have to accept as it is, I guess. I use Rakuten Mobile myself, so in situations like this, having Wi-Fi available really does feel reassuring.
Wrapping Up
To sum up, KAI Beppu struck me as a hot spring ryokan whose main appeal is an indoor bath with Usuki-yaki tile walls and kaiseki cuisine making the most of seafood from the Bungo Channel. Touches like the regional Kakishibu no Ma room and the local-style entertainment also stood out to me as features that really value the sense of place.
In terms of access, it's apparently about a 10-minute walk from Beppu Station, which makes it seem like a place that's easy to reach even for someone like me who doesn't drive. The Rakuten Mobile signal check came back with a C rating, so if that's a concern for you, it's probably a good idea to check it yourself using the official tool.
